Rituximab

Introduction

Rituximab is a monoclonal antibody used to treat certain types of cancer and autoimmune diseases. It works by targeting and destroying specific cells in the immune system, helping to manage conditions like non-Hodgkin’s lymphoma, chronic lymphocytic leukemia, and rheumatoid arthritis. Rituximab is administered under medical supervision, usually through intravenous infusion. This medicine is highly effective in slowing disease progression and improving overall quality of life in patients with these conditions.

Rituximab binds to a protein called CD20 found on B-cells (a type of white blood cell). This binding triggers the destruction of these cells, helping to treat cancers like lymphoma and leukemia, as well as autoimmune diseases by reducing the immune system`s overactivity.
